Hi, just purchased a Samsung LED TV 56 serie (5203 then another number below: 6203) and when setting up, I stupidly had it search for a channel source, unnecessarily. I am using Wi Fi only. No cable, no antenna. Now my home screen interface on Smart TV mode has an ugly TV icon (top left) with snow fuzz. It is constant and makes for a very ugly/unfriendly interface. How do I get rid of this?
